- Summary: Basic pruning guide
Pruning is a skill that every gardener needs to master -from home gardener to tradesman to professional.
There are thousands of different plants and every species needs to be
pruned differently -depending upon the location and situation it grows
in. All too often, plants are pruned poorly, leaving them unsightly and
unhealthy. Bad pruning can destroy the health and aesthetics of a
garden; but good pruning can enhance it.
Comment from John Mason Dip Hort Sc, FIOH, FCIH, FPLA
"All too often, people ask me if I can recommend a gardener who
can prune properly, because their current gardener just can't. The skill
of pruning starts with a good foundation, then builds over many years
with experience and through observing the way plants regrow after you
prune them. Over my 50 years in horticulture, I have seen a decline in
the skill and expertise being practiced by gardeners. This course is an
opportunity for you to set yourself on the path to gaining a skill that
will set you above most others working in horticulture today".
